Driver assistance system

A driver assistance system for assisting a driver when operating a vehicle F in a transportation route network, the system comprising:

• a first interface to provide navigation data ND relating to the transportation route network;
• a position detection unit to detect a position PF of the vehicle F;
• a second interface to provide at least following first data D1 relating to objects O1i, the objects O1i being arranged along transportation routes of the transportation route network, where i=1, 2, . . . , I, I≥1:
• object type OA(O2l), position POS(O1i), and risk index INDEX(O1i);
• a sensor system to scan current surroundings of the vehicle F at the position PF in order to generate surroundings data U(PF);
• a first evaluation unit to determine second data D2 relating to objects O2l based on the surroundings data U(PF), wherein the second data D2 relating to objects O2l at least include following information, wherein l=1, 1, 2, . . . , L, L≥0:
• object type OA(O2l), position POS(O22), and risk index INDEX(O2l), wherein the INDEX(x) indicates a risk for the vehicle F and/or its occupants in a collision with a respective object x;
• a fusion unit to match and fuse the first data D1 and the second data D2 to form third data D3=D3(D1, D2), wherein the third data relate to objects O3y which result from matching and fusing of the first data D1 and the second data D2 from objects O1i and O2l, where v=1, 2, . . . V, V≥1, V≤I+L, and O3v ∈{O1i, O2l}, and wherein risk indices INDEX(O3v) are assigned to the objects O3v based on risk indices INDEX(O1i) and INDEX(O2l);
• and
• an open-loop and/or closed-loop control unit to execute at least one assistance function UF in order to assist operation of the vehicle F, wherein the at least one assistance function UF is executed depending on the third data and the navigation data ND, UF=UF(D3, PF, ND).
